di-u-chloro-af-dichlorobis(triphenylphosphine)palladium(II)? The rest is OK
Calcium nitrate is unambiguous because Ca shows oxidation state +2 only, but iron nitrate is ambiguous. Eearlier we used ferrous and ferric to distinguish between two oxidation states, now we use Fe(II) or Fe(III) or iron dinitrate (trinitrate). Using both indications, ie iron(III) trinitrate is not an error.
tetraammineaquabromocobalt(III) nitrate or dinitrate
